[Buildroot] at91sam9260 alsa problem

[Michael Trimarchi]

Hi all

I have compiled the linux kernel (2.6.29) with EABI option disable so the 
expected compiled option is:

-mpcu=apcs-gnu

I have the same compiled option in buildroot and now the amixer and alsamixer 
works but aplay and arecord

report this error:

set_params:  Channels count non available

Compile the kernel using eabi and oabi compatible give different error.

This is the relevant part of buildroot config

BR2_ARM_TYPE="GENERIC_ARM"
# BR2_ARM_EABI is not set
BR2_ARM_OABI=y
BR2_ARCH="arm"
BR2_ENDIAN="LITTLE"
BR2_GCC_TARGET_ABI="apcs-gnu"

#
# Target options
#

#
# Preset Devices
#
# BR2_TARGET_ARMLTD is not set
BR2_BOARD_NAME="at91sam9260dfc"
BR2_BOARD_PATH="target/device/Atmel/$(BR2_BOARD_NAME)"

and this is the relevant part of the kernel

# CONFIG_AEABI is not set

With other combination I can use playback and record facilites but the mixer 
doesn't
work for the size of the parameteres during kernel syscall

Best regards
Michael Trimarchi

Hi all

maybe this one is the right configuration of the machine in buildroot

BR2_ARM_OABI=y
BR2_ARCH="arm"
BR2_ENDIAN="LITTLE"
BR2_GCC_TARGET_TUNE="arm9tdmi"
BR2_GCC_TARGET_ARCH="armv4t"
BR2_GCC_TARGET_ABI="apcs-gnu"

I have seen a lot of mailing list and different people report some strange 
problem with alsa. I'm using
a 2.6.29.3 kernel revision

Hi all

I have fixed and tested the gstreamer and alsa on my platform and now all works 
perfectly

Thanks

Great, what was the problem and care to send a patch so I can integrate
it?

The problem in my case was that linux compile the alsa using
armv5te and arm9tdmi option and alsa lib was compiled with different flags. So I 
have added the option for generate the arm9tdmi and armv5te combination, 
changing the configuration option of the buildroot and add them. I don't know if 
the git includes them. BTW another problem but it's just a note for the 
developers that use gstreamer and to pay attention to compile buildroot with the 
same sanitized header of the kernel of the final kernel version on your device. 
For istance I was using the 2.6.29 and the ppoll for arm not was included and 
the gstreamer was having problem because the code use them when the buffer 
does't have data on it. Hope that was clear. I will send a patch if it is 
necessary. I don't understand why all atmel architecture that are compiled with 
this tuning don't are compiled with the armv5te and arm9tdmi combination.

Best regards
Michael
